Pressure Controller

Finally, the new pressure controller arrived. This steps down pressure from the breathing gas tank to the actual breathing regulator. The previous one was a little too fiddly and its intake pressure limit was a little too close to the pressure coming off of the breathing gas tank. This one, though weighing five times more than the smaller one, and more difficult to mount, is far superior, and its overall robusticity inspires confidence. I have to take it apart to be sure there's no grease in the system, as pure oxygen and grease can lead to combustion! Taking it apart and putting it back together, as I do with my SCUBA regulators, will be my best way to really understand how it works. It's better than looking at a schematic diagram, and better than looking at a video clip; nothing is better than carefully inspecting every element as I take it apart and then put it back together.
